It's alarming that it [Zephyr] has been a desert for decades. It is kind of amazing to finally see action.

The design is now complete. EPA and MDEQ now have a signed project agreement and expect to award the contract for the cleanup and restoration work in Summer 2017.
Sediment to remediate: 36,000 to 45,000 cubic yards
Contaminants: Total petroleum hydrocarbons, lead and other heavy metals
Method: (Relatively) dry excavation
When: 2017, 1.5 years expected duration, including habitat restoration
Partners: U.S. Environmental Protection Agency and Michigan Department of Environmental Quality
Notes: A small portion (about 1,400 cubic yards) has been characterized as hazardous for lead and will be stabilized to non-hazardous conditions before removal.
Cleanup at the Zephyr site is located in the wetlands of the former Zephyr Oil refinery just south of Holton Rd. (M120) and east of the railroad tracks. See yellow area in figure below. MDEQ is conducting additional cleanup efforts in the upland portion of the site in collaboration with the US Army Corps of Engineers.
Restoring the Muskegon Lake Area of Concern
The work to clean up and restore the Zephyr site is part of a larger effort to restore the Muskegon Lake Area of Concern. Many actors are involved in the AOC, and this video highlights habitat restoration by NOAA, some of which is occurring adjacent to the Zephyr site.
The project design is complete, and a cleanup could begin fall/winter 2016. More technical information will be provided once it's available.
